Objective-C creating a text file with a string

Question

I'm trying to create a text file with the contents of a string to my desktop. I'm not sure if I'm doing it right, I don't get errors but it doesn't work either...

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDesktopDirectory, NSUserDomainMask, YES);
NSString *desktopDirectory=[paths objectAtIndex:0];
NSString *filename = [desktopDirectory stringByAppendingString: @"file.txt"];
[myString writeToFile:filename atomically:YES encoding: NSUTF8StringEncoding error: NULL];

//Method writes a string to a text file
-(void) writeToTextFile{
    //get the documents directory:
    NSArray *paths = NSSearchPathForDirectoriesInDomains
        (NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];

    //make a file name to write the data to using the documents directory:
    NSString *fileName = [NSString stringWithFormat:@"%@/textfile.txt", 
                                                  documentsDirectory];
    //create content - four lines of text
    NSString *content = @"One\nTwo\nThree\nFour\nFive";
    //save content to the documents directory
    [content writeToFile:fileName 
                     atomically:NO 
                           encoding:NSStringEncodingConversionAllowLossy 
                                  error:nil];
